Answer:
16 minutes on the elliptical trainer and 32 minutes on the treadmill.
Step-by-step explanation:
We have the following relation for the training in both machines:
[tex] 400 cal = 9 cal/min*t_{1} + 8 cal/min*t_{2} [/tex] (1)
Where:
t₁: is the time spent on the elliptical trainer
t₂: is the time spent on the treadmill
With:
[tex] t_{1} + t_{2} = 48 min [/tex] (2)
From equation (2) we have:
[tex] t_{1} = 48 min - t_{2} [/tex] (3)
By entering equation (3) into (1):
[tex] 400 cal = 9 cal/min*(48 min - t_{2}) + 8 cal/min*t_{2} [/tex]
[tex] 400 cal = 432 cal - 9 cal/min*t_{2} + 8 cal/min*t_{2} [/tex]
[tex] t_{2} = \frac{32 cal}{1 cal/min} = 32 min [/tex]
Now, we can find t₁:
[tex] t_{1} = 48 min - t_{2} = 48 min - 32 min = 16 min [/tex]
Therefore, you should spend 16 minutes on the elliptical trainer and 32 minutes on the treadmill.
I hope it helps you!

Simplify by combining like terms
m - (2m + 5n - 3m)
Answer:
=2m−5n
Step-by-step explanation:
Let's simplify step-by-step.
m−(2m+5n−3m)
Distribute the Negative Sign:
=m+−1(2m+5n−3m)
=m+−1(2m)+−1(5n)+−1(−3m)
=m+−2m+−5n+3m
Combine Like Terms:
=m+−2m+−5n+3m
=(m+−2m+3m)+(−5n)
=2m+−5n

Step-by-step explanation:
The perimeter of a rectangular ink pad is 22 centimeters the area is 28 square centimeters
Answer
W=7
Explanation:
The formula for the perimeter for a rectangle is P = 2L + 2W
The formula for the area of a rectangle is A = LW
where L = length and W = width
P = 22 and A = 28
22 = 2L + 2W
28 = LW
Rewriting the 2nd equation L = 28/W
Substituting this into the first equation
22=2(28/W) + 2W
Reworking the equation to eliminate the denominator
22W = 2(28) + 2W2
22W = 56 + 2W2
and
2W2 - 22W + 56 = 0
Dividing by 2
W2 - 11W + 28 = 0
(W-7)(W-4)
Set each factor equal to 0 and solve each for 0
W = 4, W = 7
then W = 4

Which point could be removed in order to make the relation a function?
{(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)}
(8, 3)
(3, –6)
(–1, 8)
(–4, –2)
Answer:
(3, –6)
Step-by-step explanation:
A function is a relation where one input is assigned to exactly one output.
This means that no inputs must be repeated in the relation.
(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)
The input of '3' repeats in the relation.
By removing (3, -6), we can make the relation given a function.
Hope this helps.

Is this sequence arithmetic? -2.4,9.8,22,34.2...
Answer:
Yes
Step-by-step explanation:
9.8 - (-2.4) = 12.2
22 - 9.8 = 12.2
34.2 - 22 = 12.2
Since it increases by the same amount each time it is arithmetic

Step-by-step explanation:
3x - y = -1
-3x -y = 5
x = y =
Answer:
Step-by-step explanation:
Step 1: Solve3x-y=-1 for y
3x-y=-1
3x-y+-3x=-1+-3x (add -3x to both sides)
-y=-3x-1
-y/-1=-3x-1/-1 (divide both sides by -1)
y=3x+1
Step 2: 3x+1 for y in -3x-y=5
-3x-y=5
-3x-(3x+1)=5
-6x-1=5 (simplify both sides of the equation)
-6x-1+1=5+1 (add 1 to both sides)
-6x=6
-6x/-6=6/-6 (divide both sides by -6)
x=-1
Step 4: Substitute -1 for x in y=3x+1
y=3x+1
y=(3)(-1)+1
y=-2
ANSWER: x=-1, and y=-2
The square root of -72
'8.48528137 i' or 'unidentified'
-72 isn't actually possible because a positive number times a positive number is always a positive and a negative number times a negative number is always a positive number. So you could say "unidentified".
But in HiGh sChOoL you'll learn about imaginary numbers (according to my teachers), and how it works is; basically just find the square root of 72 and write 'i' after. 'I' stands for imaginary number.
Madison’s manicure cost $25.90. She wants to leave a 15% tip. Which of the following is closest to the amount of the tip she wants to leave?
A. $2.00
B. $3.00
C. $4.00
D. $5.00
Answer:
C) $4.00
Step-by-step explanation:
Here's how I did it:
So we're trying to find 15% of $25.90... we can say that the $25.90 is 100% of Madison's Manicure... 100% can also be written as 1.0... why? well if 1.0 is 100%, then we can say any other percentage is proportionate to this... for example... 0.25 is 25% of 1.0... In this case... we are trying to add an additional 15% to the 100% price of the manicure... (Remember... with our proportion we can say that 115% is the same as 1.15) If we take our proportion:
1.15 x 25.90 = 3.89
4.00 is the closest to 3.89
therefore the answer is C) $4.00
